The present invention relates to a hybrid driving module, in which an input member is aligned in a radial direction and/or an axial direction by a rotor hub, and thus the hybrid driving module may be easily assembled and ensure the high axial balance and the operability and durability of the engine clutch. In the hybrid driving module, the input member may be aligned at least in the radial direction or in the axial direction by a central shaft extension part of the rotor hub. A bearing configured to support a rotation and thrust may be installed between the central shaft extension part and the input member. The input member may be supported to be rotatable relative to a housing. The input member may be aligned in the radial direction and/or the axial direction by the housing.

A new method of manufacturing a torque-transmitting component is provided. The method includes providing a flat blank to a transfer press having a plurality of stations and performing a plurality of pressing operations, in which the flat blank is formed into a cup shape, rough splines are formed on the cup shape, and the rough splines are further pressed to define smooth splines. The component includes a continuous smooth inner diameter defined by a punch of the transfer press and a plurality of smooth splines defined by a die of the transfer press. The minor diameter of the splines is not machined to form the splines.

The present invention provides a hybrid driving module which fixes a rotor while hub ridges of the rotor are provided on a rotor hub and firmly provides the hub ridge to the rotor hub so as to enable vibration noise to be reduced, and which has a structure in which the hub ridges support the rotor in a state in which the hub ridges are fastened to the rotor hub at which the rotor is provided. The hybrid driving module may further include a ridge fixing structure that prevents the hub ridge from separating from the rotor hub. For example, the ridge fixing structure may be a ridge snap ring. The hybrid driving module may further include an elastic body that elastically presses the hub ridge toward the ridge snap ring. The elastic body may elastically press the rotor in the axial direction. The elastic body may also serve as a return spring of the piston plate of the engine clutch.

On one side in the axial direction of the plurality of friction plates of the one-side clutch, a radial section of the piston of the one-side clutch and a radial section of the piston of the other-side clutch are arranged in parallel in the axial direction. Pressure-receiving sections of the pistons of the one-side clutch and the other-side clutch and bearing sections of the pistons of the one-side clutch and the other-side clutch are aggregated and arranged on a radially inner side.

A drive module for a vehicle includes an input extending along an axis and configured to be driven by an engine. An electric motor has a rotor carrier hub configured to be rotated about the axis. The rotor carrier hub is non-rotatably connected to a torque converter cover and is selectively coupled to the input via a clutch. The rotor carrier hub has an inner surface defining an interior, an outer surface defining an exterior, and a plurality of holes extending through the rotor carrier hub from the inner surface to the outer surface to enable oil to transfer from the interior to the exterior. This provides a controlled and relative constant oil flow for cooling the drive module.

In a power transmission apparatus, an auxiliary clutch plate different in diameter from driving and driven clutch plates located in a clutch housing. When the driving and driven clutch plates are pressed against each other, the auxiliary clutch plate is pressed to enable transmission of a driving force of an engine to a driving wheel. When a pressing force exerted on the driving and driven clutch plates is released, a pressing force exerted on the auxiliary clutch plate is released to cut off transmission of the driving force of the engine to the driving wheel.

Particular embodiments disclosed herein provide a joint of a tray arm assembly, comprising a joint body, a shaft configured to rotate relative to the joint body about a longitudinal axis of the shaft, and a slip clutch assembly, comprising a clutch stack, including a plurality of first clutch plates keyed to the shaft and a plurality of second clutch plates keyed to the joint body. The clutch stack further comprises a spring configured to selectively exert a force on the clutch stack, wherein the force compresses the clutch stack causing a friction between the plurality of first clutch plates and the plurality of second clutch plates with respect to a rotation of the shaft relative to the joint body.
